The attack consisted of a car bomb set off outside the Nedbank Square building on Church Street at 4:30pm on a Friday. The target was South African Air Force (SAAF) headquarters, but as the bomb was set to go off at the height of rush hour, those killed and wounded included civilians. The bomb went off ten minutes earlier than planned, killing two ANC operatives in the vehicle, Freddie Shangwe and Ezekial Maseko. At least 20 ambulances took the dead and wounded to hospital.
